SPECIFICATION forming part of LettersPatent No. 283, 47, dated August 14, 1883,

' Application filed December 8. 1882. (No model.)

To all iohom itfinay concern:

Be it known that I, J OHN S. HULL, a citizen I of the United States, residing atBaltimore,

which vaporized fluid or. oil is used as fuel;

and it consists in certain improvements there in, as will be first duly described hereinafte'r, and then particularly pointed out in the claims.

Referring to the drawing by letters, A B O D represent tanks of a large size, while F, G,

valves to, withthe air-tank A.

and H are smaller tanks.

a is an ordinary air-pump, the airfrom which is forced into the tank A through a which is providedwith a valve, 66".

A is a water-main connecting-pipe, (supplied with water under pressure) which is provided with valves AKA", and has short pipes connecting it with tanks ,B 0, each of which connections has a valve marked, respectively, A? and A 5 It (the pipe A leads to a tank, A, set at a considerable elevation, and which is connected, by means of a pipe, (0, having This pipe to communicates, by means of a four-waycouppi pe,: a,

ling, with a pipe, J, as shown; This pipe J has connection with each of the tanks A B (J D F G H by means of branches marked,

respectively, a" (just described) B c D f g h,

which are provided, respectively, with valves a" b 0? cl f g h, by means of which the supply of air 'canbe cut oiffrom any or all of the tanks, if desired- B is also a wateripe, connecting with a suitable supply under pressure-as, for instance, the city mains.

O is-a spigot for emptying tlletank O, and O is awater-gage attached thereto. The tanks G and D are each provided with a filler-opening having in it a vent-valve, 0*.

Eis a pipe, which may be denominated the main supply-pipe, connected by branches 0 Dtf g k with the tanks 0, D, F, G, and H,

respectively. It has also a branch, 6 upon necting-directly withthe main supplypipe E as may be desired. The tanks F G H each supply aburner, as F G" H, by means of branches f g h",,each provided with a valve, as f 9* h, as shown. The main supply-pipe E is supplied with valves I I I 1 whose purpose will be hereinafter explained. The burners may be of any desired style to be used to heat fire-pots, stoves, 85c.

The operation of my device is as follows: Air, being forced into the tank A by the pump a, may be led to all the rest of the tanks, or as many as desired, by a proper manipulation of the valves. This will force the oil contained vin the tank D into the smaller tanks F G H, causing them to be filled and the oil in them to be forced by the compressed air to the burners. Each one of these small tanks may be entirely out off from the others, which will servea twofold purpose-viz., to enable it to be definitely ascertained how much oil each burner uses, and to allow all the rest of the burners to be used should one of them by accident be broken or injured and require repairing.

A series of burners, as at 6, may also be used, obtaining their supply directly from the tank D through the pipe E. The branch or connection z leading from the pipe E to the pipe f may also be used in connection with the pipes g h, and serves, by opening its valve and closing the valve 2' in the pipe f below the co1mection,to supplythe burners with oilldirect from pipe,E when, by

accident, the tank is out of order.

In cities having a water-supply under pressure it is desirable to utilize such pressure, and this I do by allowing the water t0=passfr0m the main through pipe Binto tank B. From thence it may pass into the tank 0 under the oil therein contained, and the oil, being of less specific gravity than water, will remain above the water and be forced into the main supplypipe E. The height of water, and consequently the depth of the oil, will be indicated by the gage 0 I also allow water to pass from the main through the pipe A to the elevated tank A, and thus utilize the height of the column of water contained in this supply-pipe A 'by shutting the valve A and opening the valve A leading to tank 0. The pressure of this column is also supplemented by the pressure of air through the pipe a into said tank A.

If it is desired to entirely shut off one or more of the burners and its individual supplytank, this can be done by closing the two valves,

repairs may be made on the interrupted burner. My improvements as hereinbefore described may be employed to supply fluid to tinners firepots, using any approved burner, as at F, or to a series of cooking or heating apparatus of any'suitable style, with burners, as at G H, or for heating in soldering' cans, or with cansoldering machines-in fact, with any and all styles of vapor-burners.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. The combination of the air-pipe J, supplied by a suitable air-forcing apparatus with air under pressure, the oil-supply pipe E, a series of individual tanks, F G H, branch pipes from each of said pipes to each of said tanks,

as P1, in the pipe E. r The action of the other burners will be uninterrupted by this, while a series of burners connected with and supplied by said tanks, and means, substantially as described, whereby any one or more of said burners and its supply-tank may be out out from the air and fluid supply at will, as set forth. 7 v

2. The combination,with a burner or series of burners, of the pipe E, tanks 0 and D, waterpipeAZ air-pipes c J, and the air-pump, as set forth.

3. ,The combination, with a burner or series of burners and a suitable supply-tank, as at O,

.of the airpipes c J, the air-forcing apparatus,

the pipe A", and tank A, placed in an elevated position, as set forth.

4. The combination of the air-pump a, pipe
